The Iranian foreign minister has written to the UN chief requesting a plane for evacuation of the wounded

Iran today requested help from the UN to send a plane to Yemen to evacuate the wounded from Saturday’s deadly air strike on a funeral ceremony.

The country’s foreign minister Mohammad Javad Zarif expressed "shock and indignation" over the air strikes in Sanaa, AFP reported.

"In view of the gravity of the situation in Yemen and the devastation caused by the attacks against the funeral hall, the Iranian Red Crescent Society is proposing to arrange for humanitarian assistance, including medical supplies, to the Yemeni people and evacuating the injured to hospitals in Iran," Zarif wrote in a letter to UN Secretary-General Ban Ki-moon, AFP reported.

Iran-backed Houthi rebels have blamed the Saudi-led coalition for the attack that killed more than 140 mourners and injured over 525.

"Not only Saudi Arabia, but also those who have supported the aggression by the Saudi-led coalition against Yemeni people should be held accountable for the war crimes perpetrated in Yemen over the past year and a half," Zarif wrote, AFP reported.

Ban earlier condemned the attack and called for an investigation of the air strikes.

Canada has also called for a prompt investigation into the air strikes, that are one of the deadliest since the Saudi-led coalition launched a military campaign against the Shiite insurgents in March 2015.

“The Saudi-led coalition must move forward now on its commitment to investigate this incident," Canadian foreign minister Stephane Dion said in a statement condemning the attack, AFP reported.

"Canada calls on all parties in Yemen to avoid an escalation of violence as a result of this incident."

Dion said. "Canada urges all parties to abide by their obligations under international humanitarian law, and to commit to political dialogue and to a lasting cessation of hostilities to halt the tragic loss of civilian life."
